Deleting unused maps / voices / languages

Go to the directories as described in the topic "Where and how to store new maps / voices / languages" using Mio Transfer Hack.

Highlight the files you want to delete. Make sure you selected the right files. Click on the delete button located just above the 2 windows, the second from the left. You can also push the delete button on your keyboard directly.

Another method is deleting your files through a card reader. Ofcourse this only applies to files located on a sd card and not your flash disk.

How accurate are Mio maps? / Where to report map errors.

Mio products use Tele Atlas maps. Tele Atlas maps are very detailed and even the smallest roads are usually captured.

Wrong route advice is possible:

because route calculations are made to match your route calculation favorite choice (fastest, shortest, economical, etc...), with the available roads on your way and their 'grade' in the maps database (from highway to tracks). In some rare and particular cases some roads are not set with the actual grade because of speed limit modifications, road works, addition of traffic lights.

traffic situation changes constantly in all countries. Tele Atlas constantly updates its map data but due to the huge amount of kilometers to be monitored, not all roads can be surveyed (this means checked in reality) at the same time. The main roads are surveyed first. This means that mistakes may still appear for a while on smaller roads in map data.

not all countries have yet been captured with the same amount of details. If you are interested in a particular area and would like to verify if it's included in map data or not, you can browse to Mappy (this website uses the same Tele Atlas maps) and enter your address. If the area is covered, it will be shown on Mappy. If not it means the area you are looking for is not covered yet in the map data.

Since the map data belongs to Tele Atlas, mistakes in the database cannot be updated by Mio. Errors can be reported via the link: Tele Atlas MapInsight. Follow the link and locate and define your problem.

Necessary updates are shown in black. In case you have to install MioMap v3 updates (first option) it is best to do these updates alone and start up the tool for a second time to update other items. Important: map updates are updates in the maps due to bugs. The map data itself is not updated.

If your device doesn't need an update, the following message will appear:

I've copied all maps to an SD card, but my device can't find them.

If you use your desktop computer's SD card reader to copy the maps to an SD card, make sure to copy it into the right folder.

In the root of the SD card, create a folder named MioMap. In that folder, create a subfolder named Maps.

Copy all the maps there and your device will find them.

How can I reset my C710?

When your device is not working properly, you can reset it.

Always try a soft reset first (pos 4 on picture). This will only reset the software. To perform a soft reset, use a fine pointy object to push the little round button on the bottom of the device, between the earphones connector and USB port.

If the soft reset did not solve your problem, a hard reset (pos 5 on picture) might. It resets all software on the device. To perform a hard reset, put the off/on switch on the bottom of the device in the off position and wait for a moment. After that, put the switch back in the on position.

How can I see the type of map coverage on my device? (MRE or full coverage)

Instructions to see the map coverage of your device.

In the MioMap v3 main menu, tap the settings button (top right corner of the screen).

In the settings menu, tap the About button (lower right corner of the screen)

In the About menu, tap the Maps button.You now see a list of all countries, installed on your device. For countries where only MRE coverage is available, you'll see (MRE) (i.e. Major Roads of Europe) behind the name of the country. All other countries have full coverage.

How do i change the map colors? (Schemes)

Mobile Registry Editor is an application that can be used to edit the registry of your Pocket PC or Smartphone (Windows Mobile device). With it you can remotely edit the registry using your desktop keyboard and mouse as opposed to using your stylus/keypad on your PDA or phone. It's built as a Windows application which has been modeled after Regedit (with a few extra features such as favorites, value size, column sorting etc...)

It has been tested with my Pocket PC and Smartphone on Windows XP/2000 and requires the .NET Framework 1.1 to run.

Which SD cards are usable?

(Table above provided by Mio US)

There are a lot of issues with 4gb cards. For best performance and full use of the 4gb format the 4gb sd cards FAT32!! This does not mean that your card will work. Some cards are just incompatible with Mio devices. That's why i created this little topic.

Look below for cards (not) useable collected by me todate from input given by readers from this site.

I have no means and no intentions to check if all the data provided by others are correct. I have to believe that the info is ok, unless proven otherwise. Therefore i will take no responsibility what so ever, if you bought a card which is not usable for your device. But if you don't get it working, please send me a mail or sign my guestbook and i will correct my list.

Some people complain about the sound when spoken to through the Bluetooth connection.

On the bottom, to the right, position 6 in the picture, the very small hole is your microphone. In your PNA car holder there is also a small hole on the same spot. When you click your Mio into the car holder the audibility for the people you talk to decreases considerably.

So what can be done about that?

Someone on the Dutch Mioforum.be, alias jaspernl, had the brilliant idea to modify the microphone hole of the car holder and drill a bigger hole of approximately 4,0mm. (Original about 2,0mm). Mind you, we are talking about the car holder and not your Mio device.

The modification has been done by several people and the audibility has improved considerably.

I will take no responsibility if you do this and something goes wrong. But drilling a little hole is not rocket science. I did it myself also. There are also some pictures on the link below.
